Our successes are built on the foundation of having the number one-ranked franchises in each of our end markets, technical leadership, infrastructure domain expertise, and trusted client relationships. Our investments in the Advisory and Program Management businesses, as well as in technology and AI enable us to scale these attributes, expand our addressable market, deliver even greater value to clients, and build an even stronger and more durable moat – all of which underscore our confidence in achieving our financial objectives.” “Across our markets, clients are increasingly turning to us to deliver their biggest and most critical infrastructure projects and programs,” said Lara Poloni, AECOM’s president. “From our selection as a preferred bidder on Scottish Water’s new multi-billion-dollar investment program to our selection as Delivery Partner to the Games Independent Infrastructure and Coordination Authority for the Brisbane 2032 Olympic and Paralympic Games, we consistently win what matters through our unrivaled competitive advantages. These advantages are enhanced by our AI and technology investments, which have been instrumental in key wins and favorable commercial model discussions with clients. Our teams are energized by these investments and by the opportunity to redefine how infrastructure is delivered.” 1 “Our strong performance, record backlog and increased guidance demonstrate we are creating significant competitive differentiation in the market,” said Gaurav Kapoor, AECOM’s chief financial and operations officer. “Year after year we have expanded our productivity, which is evident in the persistent NSR and profit per employee growth we have delivered for the past six years. Importantly, through the investments we are making, the opportunity for this trend to continue has never been greater. We operate with a strong balance sheet, including no debt maturities for several years, and an attractive cost of capital. As a result, we continued to execute on our returns-based capital allocation policy in the quarter, which included returning more than $340 million to shareholders.” First Quarter Highlights: · Reflecting as reported GAAP performance from continuing operations, first quarter revenue declined 5% to $3.8 billion, operating income declined 7% to $222 million, net income declined 21% to $140 million and diluted earnings per share declined 20% to $1.06. · Net service revenue 2 increased 2%; net service revenue increased by 5% after adjusting for fewer working days compared to the prior year first quarter, highlighted by 9% growth in the Americas segment. · The segment adjusted 1 operating margin 4 and the adjusted 1 EBITDA margin 6 increased to 16.4% by 100 basis points and 80 basis points, respectively. ‒ Our margins include the investments in the Company’s AI and technology teams and capabilities, in growing its Advisory teams, and in record business development. · Adjusted 1 EBITDA 5 increased by 6% and adjusted 1 EPS decreased by 2%. ‒ Adjusting for the lower tax rate in the prior year period, adjusted EPS increased by 8%. · Total backlog 8 increased by 9% to a record high, highlighted by a 1.5 book-to-burn 9 ratio. ‒ The Company delivered a 21 st consecutive quarter with a book-to-burn ratio in excess of 1.0. ‒ The Americas design business had a 1.0 book-to-burn ratio despite the unprecedented 43-day U.S. federal government shutdown that resulted in award delays. ‒ The pipeline of opportunities increased by double digits to a new record, including growth in both the Americas and International segments, with the fastest growth in the earlier stages of the pipeline demonstrating strong long-term demand trends. Cash Flow, Capital Allocation and Raised Repurchase Authorization · Free cash flow 7 was $42 million and the Company returned more than $340 million to shareholders through repurchases and dividends in the quarter. · After the quarter ended, the Board of Directors approved an increase to the share repurchase authorization to $1 billion. ‒ Since the initiation of its repurchase program in September 2020, the Company has returned nearly $3.4 billion of capital to shareholders through repurchases and dividends. · The Company maintains a strong balance sheet with net leverage 10 of 1.0x. Fiscal 2026 and Long-Term Financial Guidance · The Company raised its fiscal 2026 earnings guidance, which reflects the outperformance delivered in the design business in the first quarter, the benefits of our capital allocation strategy, a lower than previously expected tax rate, and a record backlog and pipeline across the enterprise, which creates strong full year visibility. · As a result, the Company’s guidance, which includes the Construction Management business, now includes expectations for: ‒ Adjusted 1 EPS of between $5.85 and $6.05, as compared to $5.65 to $5.85 previously. ‒ Adjusted 1 EBITDA 5 of between $1,270 million and $1,305 million, as compared to $1,265 million and $1,305 million previously. ‒ Organic NSR 2 growth of 6% to 8%, which excludes the expected approximately 200 basis point impact of fewer working days in fiscal 2026. ‒ A segment adjusted operating margin 4 of 16.8% and an adjusted EBITDA 6 margin of 17.0%, which are materially consistent with prior expectations. ‒ Free cash flow 7 of approximately $400 million. ‒ An average fully diluted share count of 131 million, which does not include any potential future benefits from capital allocation actions not yet taken, including potential repurchases. ‒ An adjusted effective tax rate of approximately 20 – 22%, as compared to 22 – 23% previously. · In addition, the Company reiterated its long-term financial targets, which includes its expectation to deliver a 20%+ margin exit rate by fiscal 2028 and to grow adjusted 1 EPS at a 15%+ CAGR from fiscal 2026 to fiscal 2029. · See the Regulation G Information tables at the end of this release for a reconciliation of non-GAAP measures to the most directly comparable GAAP measures. 2 Business Segments Americas Revenue in the first quarter was $3.0 billion, a 4% decrease from the prior year due to a reduction in pass-through revenue. Net service revenue 2 in the first quarter was $1.1 billion, a 9% increase from the prior year when adjusted for the impact of fewer working days in the period, or 6% on an as reported basis at constant currency. Growth was strong in both the U.S. and Canada. Operating income increased 9% over the prior year to $214 million and on an adjusted 1 basis increased 13% to $222 million. The adjusted operating margin on net service revenue increased by 120 basis points over the prior year to 19.9%, a new first quarter high. This performance reflects the benefits of strong growth and a continued focus on driving operating efficiencies across the business. Backlog in the Americas segment grew 3% to a new record high, driven by a 1.0 book-to-burn ratio 9 . The Americas design business had a 1.0 book-to-burn ratio despite award delays resulting from the unprecedented and now resolved 43-day U.S. federal government shutdown during the quarter. International Revenue in the first quarter was $854 million, a 5% decrease from the prior year. Net service revenue 2 was $736 million, which was materially unchanged with the prior year when adjusted for the impact of fewer working days in the period, or a 3% decrease on an as reported basis at constant currency. Operating income decreased by 6% over the prior year to $76 million and on an adjusted 1 basis was effectively unchanged at $81 million. The adjusted operating margin on net service revenue increased by 20 basis points to 11.0%, which reflected a combination of strong execution, operational efficiencies, and a focus on high returning markets and clients. Backlog in the International segment grew 25% to a new record high, driven by a 2.3 book-to-burn ratio 9 and included substantial wins in each of the Company’s International regions. Construction Management Strategic Alternatives Update AECOM has completed the comprehensive review of strategic alternatives for its Construction Management business. The Company has concluded that it will continue to own and operate the business and believes it is exceptionally well positioned for the future. The Construction Management business is an industry leader with a strong backlog and pipeline, great teams of professionals, and is widely recognized by its clients for its track record of delivering the largest and most iconic projects in its markets. Tax Rate The effective tax rate was 19.7% in the first quarter. On an adjusted 1 basis, the effective tax rate was 21.5% in the first quarter. The adjusted tax rate was derived by re-computing the quarterly effective tax rate on adjusted net income 11 . The adjusted tax expense differs from the GAAP tax expense based on the taxability or deductibility and tax rate applied to each of the adjustments. Resolution of a Legacy Matter After the quarter ended, AECOM agreed in principle to settle a legacy project-related matter that was acquired with the Company’s 2014 acquisition of URS Corporation. As a result, the Company expects to receive approximately $50 million in cash this fiscal year and recorded a $61.8 million non-cash loss in discontinued operations in the fiscal first quarter.

Although we believe that the expectations reflected in our forward-looking statements are reasonable, actual results could differ materially from those projected or assumed in any of our forward-looking statements. Important factors that could cause our actual results, performance and achievements, or industry results to differ materially from estimates or projections contained in our forward-looking statements include, but are not limited to, the following: our business is cyclical and vulnerable to economic downturns and client spending reductions; government shutdowns or other funding circumstances that cause governmental agencies to modify, curtail or terminate our contracts; losses under fixed-price contracts; limited control over operations that run through our joint venture entities; liability for misconduct by our employees or consultants; failure to comply with laws or regulations applicable to our business; maintaining adequate surety and financial capacity; potential high leverage and inability to service our debt and guarantees; our capital allocation strategy, including ability to continue payment of dividends and stock repurchases; exposure to political and economic risks in different countries, including tariffs, geopolitical events, and conflicts; currency exchange rate and interest fluctuations; retaining and recruiting key technical and management personnel; legal claims; inadequate insurance coverage; environmental law compliance and adequate nuclear indemnification; unexpected adjustments and cancellations related to our backlog; partners and third parties who may fail to satisfy their legal obligations; managing pension costs; AECOM Capital real estate development projects; cybersecurity issues, IT outages and data privacy; risks associated with the benefits and costs of the sale of our Management Services and self-perform at-risk civil infrastructure, power construction and oil and gas businesses, including the risk that any purchase adjustments from those transactions could be unfavorable and result in any future proceeds owed to us as part of the transactions could be lower than we expect; risks associated with strategic initiatives, including AI investments and potential acquisitions and divestitures; as well as other additional risks and factors that could cause actual results to differ materially from our forward-looking statements set forth in our reports filed with the Securities and Exchange Commission. Any forward-looking statements are made as of the date hereof. We do not intend, and undertake no obligation, to update any forward-looking statement.      Non-GAAP Financial Information    This communication contains financial information calculated other than in accordance with U.S. generally accepted accounting principles (“GAAP”). The Company believes that non-GAAP financial measures such as adjusted EPS, adjusted EBITDA, adjusted EBITDA margin, adjusted net/operating income, segment adjusted operating margin, adjusted tax rate, net service revenue and free cash flow provide a meaningful perspective on its business results as the Company utilizes this information to evaluate and manage the business. We use adjusted operating income, adjusted net income, adjusted EBITDA, adjusted EBITDA margin, and adjusted EPS to exclude the impact of certain items, such as amortization expense and taxes to aid investors in better understanding our core performance results. We use free cash flow to present the cash generated from operations after capital expenditures to maintain our business. We present net service revenue (NSR) to exclude pass-through subcontractor costs from revenue to provide investors with a better understanding of our operational performance. We present segment adjusted operating margin to reflect segment operating performance of our Americas and International segments, excluding AECOM Capital.  We present adjusted tax rate to reflect the tax rate on adjusted earnings. We also use constant-currency growth rates where appropriate, which are calculated by conforming the current period results to the comparable period exchange rates. 4 Our non-GAAP disclosure has limitations as an analytical tool, should not be viewed as a substitute for financial information determined in accordance with GAAP, and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. A reconciliation of these non-GAAP measures is found in the Regulation G Information tables at the back of this communication. The Company is unable to reconcile certain of its non-GAAP financial guidance and long-term financial targets due to uncertainties in these non-operating items as well as other adjustments to net income. The Company is unable to provide a reconciliation of its guidance for NSR to GAAP revenue because it is unable to predict with reasonable certainty its pass-through revenue. In addition, the Company is unable to provide a reconciliation of its guidance for financial metrics excluding the Construction Management business due to uncertainties in these non-operating items as well as other adjustments to these measures. 5 AECOM Consolidated Statement of Income (unaudited - in thousands, except per share data) Three Months Ended December 31, 2025 December 31, 2024 % Change
